Abstract

The invention discloses a scale-inhibition copper-based catalyst alloy and a preparation method thereof. The catalyst alloy comprises the following components in percentage by weight: 40%-70% of Cu, 5%-20% of Ni, 10%-35% of Zn, 5%-30% of Sn, 0.5%-20% of Ag, 0.1%-8% of Fe, 0.01%-2% of Sb and 0.05%-5% of Mn, wherein the components are chemically compounded to form a columnar crystal alloy directionally growing along an S100 crystal axis. The scale-inhibition copper-based catalyst alloy is used for inhibiting the formation of water scale by virtue of an advanced weak-current composite scale-inhibition mechanism on the premise that chemical components of fluid are not changed and has very strong water scale dissolving capacity; the additional maintenance does not need to be carried out in an operation process, the magnetism, the electricity and an additional power supply are not required.

Description

technical field [0001] The invention relates to an alloy material, in particular to a copper-based catalyst alloy for scale inhibition and a preparation method thereof. Background technique [0002] The problem of fluid fouling exists widely in systems involving fluid transmission and circulation in petroleum, thermal power and other industrial and civil fields. In most cases, the fluid in the industrial pipeline system is in the state of simple substance or mixed solution, and the solubility of the solute is related to the composition of the solution, total salinity, total ion concentration, temperature, pressure, gas partial pressure, PH value, flow rate related to many factors. Once the dissolution conditions of the solution system change, the solute solubility will also change accordingly. When the solubility decreases, so that the solute content is in a supersaturated state, the solute will precipitate. Scaling occurs when precipitated solutes deposit on vessel walls...
